Subject: [PATCH 1/3] feat(strings): add randomColor function for generating
 hex colors

Implemented randomColor() function using Test-Driven Development (TDD):
- Generates random hex color codes in format #rrggbb
- Returns 6-digit lowercase hex values with leading zeros
- Added comprehensive tests validating format and randomness
- All tests pass successfully

The function uses Math.random() to generate random RGB values and
formats them as a standard hex color string.
